HARRY SCHEIB, OF PHILADEL'EIIIA, AND TILLIAM A. AUSTIN, OF WAYNE, PENN- SYIIVNIA, ASSIGNORS TO BALDVJIN LOCOB'IOTIVE VJOBKS,

OF PHILADELPHIA,

PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA..

LOCOMOTIVE.

To all whom 'it may concern.'

Be it known that we, HARRY Sor-11MB and ViTiLLL-iir A. AUSTIN, citizens of the United States, residing in Philadelphia, Pennsylvania, and Vayne, Pennsylvania, respectively, have invented certain Improvements in Locomotives, of which the following is a specification,

Our invention relates to certain improvements in compound locomotives, preferably of the articulated type, in which there are two sets of cylinders at the forward end of the locomotive, and two or more cylinders at the point intermediate of the ends of the locomotive.

rFhe object of our invention is to so design the locomotive that it can be used either as a triple expansion locomotive or a compound locomotive in which the intermediately located cylinders are the high pressure cylinders and the forward cylinders are the low pressure cylinders.

Referring to the accompanying drawings :*Figure l, is a longitudinal sectional view of suflicient of a locomotive to illustrate our invention; Fig. 2, is a diagrammatic plan view; Fig. 3, is an enlarged sectional view on the line 3-3, Fig. l; Fig. t, is an enlarged sectional View on the line 4 4, Fig. l; and Fig. 5, is a view of a modification.

A is the boiler of the locomotive, B is the rear frame and B is the forward frame; the two frames being pivoted together at as in the ordinary type of articulated locomotives. In the present instance the boiler A is suitably supported on the rear frame B and overhangs the forward frame B.

C is the high pressure cylinder located on one side of the locomotive intermediate of the ends thereof.

D is the intermediate cylinder located on the side of the locomotive opposite to the high pressure cylinder, as clearly illustrated in Fig. 2, and E, E are two low pressure cylinders located at the forward end of the locomotive.

a is the steam supply pipe leading from the dome of the boiler and communicating with the 'live steam .ports of the high pressure cylinder C.

c, c are pipes forming communication between the exhaust port of the high pressure cylinder C and the intermediate cylinder D.

Specification of Letters Patent.

Application filed February 1l, 1919.

Fatented Dec. 20, 1910.

Serial Eo. 543,838.

' In the present instance there are steam passages in the saddle Z) with which these pipes c, c communicate, and in the intermediate combustion chamber a of the boiler is a pipe 02 which is connected to passages in the saddle, which in turn connect with the cylinder D through the passage c, as clearly shown in Fig. et, and in this pipe we preferably arrange an automatic reducing valve.

The exhaust passage from the intermediate cylinder D communicates through a pipe Z with a passage in the saddle Z), which in turn communicates with a pipe d leading to the forward end of the locomotive. The pipe d passes through a section of the boiler, which is usually the feed water section, and enters the smoke box a2 where it is connected to a sliding and universally jointed pipe cl2 which communicates in turn with thepassages in the front frame -B located between the two cylinders E, E, as clearly shown in Fig. 3. The passage in the said frame B communicates with the steam spaces or cylinders E, E through pipes e, e respectively, and the exhaust passages of said cylinders communicate with pipes 7 which in turn connect with a pipe f communicating with the nozzle F located in the smoke box A2 of the boiler.

We preferably arrange the piping so that live steam will be admitted directly to the low pressure receiving pipe cl when starting.

It will be understood that the steam may be superheated as it passes from the boiler to the high pressure cylinder and from the high pressure cylinder to the intermediate cylinder, and from the intermediate cylinder to the low pressure cylinders. Any suitable superheater may be used without depart-ing from the essential features of the invention.

As shown in Fig. 2, the steam passes first to the high pressure cylinder C and then to the intermediate cylinder D, and then through the pipe CZ to the two low pressure cylinders E, E-

In some instances we may substitute for the high pressure cylinder C and intermediate cylinder D, a pair of cylinders on each side, one superimposed upon another or arranged tandem, or transversely, as desired, making in each case a six cylinder locomotive. For instance, in Fig. 5, the smaller cylinders C are the high pressure cylinders and the cylinders D are the intermediate cylinders which communicate with the low pressure cylinders at the forward end ot the locomotive; thus we are enabled to make a triple expansion locomotive which may be readily converted into a double expansion or compound locomotive, or, if desired, may be used as a six cylinder locomotive, triple eX- pansion.

l. The combination in a locomotive, of a low pressure cylinder arranged on each side of the locomotive at one end, with a high pressure cylinder and an intermediate cylinder located at a point midway between the ends of the locomotive, the piping forming communication between the several cylinders whereby the steam passes from the high to the intermediate cylinder and from the intermediate to the low pressure cylinders.

2. The combination in a locomotive of the articulated type of two frames connected together', a set of low pressure cylinders mounted on the forward frame of the locomotive, two cylinders mounted on the rear frame of the locomotive, one of said cylinders being a high pressure cylinder and located on one side of the locomotive, an inerases termediate cylinder mounted on the other side of the locomotive, with piping connecting the several cylinders forming a triple expansion locomotive.

3. rlhe combination in a locomotive having two sets of cylinders, one at the forward end of the locomotive and the other intermediate the ends thereof, the forward cylinders being low pressure cylinders, one o'l' the other cylinders being a high pressure cylinder and the other an intermediate cylinder, a boiler, a pipe leading from the boiler to the high pressure cylinder, pipes leading from the high pressure cylinder to the lintermediate cylinder, a longitudinally arranged pipe leading from the intermediate cylinder to the low pressure cylinders, and pipes connecting the low pressure cylinder with the exhaust nozzle in the smoke box of the locomotive.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
